So, simply (I'm deathly afraid of an overfill) if the transmission slips,
add more fluid in small amounts until it comfortably stops slipping. At
this point I will be able to drive the 15+ minutes to warm everything up,
and then properly check the fluid. Is this a safe conclusion?

when a problem occurs, like my hard trans cooler line having a BAD leak,

When the car was cold/off after the repair, I could see fluid on the
very
bottom of the dip stick, so I added about a quart in small increments
with
the engine running. I tried driving about 1-2 miles, and down hill it
seemed ok, but did slip a bit. Coming back up the gentle hill, it was
slipping constantly. I'm going to check the fluid level in the AM when
it's cold and see where it lies. How do I tell by the dip stick how
much
fluid is needed? I've done several fluid changes, but that's easier on
my
brain...this is new territory.
Also, what are the differences in a overfilled and underfilled trans?
How
will each one act? I've been through low once, so I kinda know how it
acts, and I'm really curious about how an overfilled tranny acts. TIA
all....
When you check fluid in the transmission when it's cold (engine started
and running so the torque converter is filled) the level of a 722.3
series transmission should roughly be 10-12 mm below the lower mark on
the dip stick. After you drive for 15+ minutes (to warm the fluid up to
normal operating temp) and check again and the level should be at or
topped up to the upper mark. The difference between the upper and lower
mark is 0.3 liters (~1/3rd qt). An under filled transmission will result
(or make worse) in slipping - especially when cold. Over filling will
result in foaming and jarring shifts when driven hard and this can do a
LOT of damage.
